TOPIC: building a Jumbo TV from standard LEDs

Hi,
I need an advice ..For one business idea I need to build a big screen consisting of 9 or even more smaller LED displays, each having say 55 inches in diameter. I would go for jumbo TV large screen but I do not have so much money.
Does anybody of you can tell me how to do that, what do I need (I am an accountant and just know somehow it can be done, I just do not know how, where, for how much, what are the limitations,...).
I would need to attach all screens to an iron backplate and cover all screens with a thin plastic film or foil to protect them from weather. Can you help me shed more light on this? To understand this more?
Thank you
Peter

You should talk to a sign shop. Standard LED TV's are not bright enough to be watchable in daylight so if it will be used in daytime hours consider that. You will need a video wall controller and custom enclosure for the TV's as well. Just a wild guess, cost $30,000 - $50,000.
